Hi Helen,
If you want to practice with some data, then I suggest
that you see HowTo #5, the data for which is also used
in our current classes.
[
afni.nimh.nih.gov]
[
afni.nimh.nih.gov]
That comes with background on the experiment, scripts,
sample data, and explanations of usage.
The earlier HowTos (like #1 or #2) have different sets
of data, and give details on the Unix T-shell commands
used for process them.
See the "howto packages" under the "Documentation" tab.
